Definitions

• Aluminum alloy products are generally produced via either shape casting or wrought processes.
• Shape casting generally involves casting a molten aluminum alloy into its final form, such as via pressure-die, permanent mold, green- and dry-sand, investment, and plaster casting.
• Wrought products are generally produced by casting a molten aluminum alloy into ingot or billet. The ingot or billet is generally further hot worked, sometimes with cold work, to produce its final form.
• the present disclosure relates to metal powders for use in additive manufacturing, and aluminum alloy products made from such metal powders via additive manufacturing.
• the composition(s) and/or physical properties of the metal powders may be tailored.
• additive manufacturing may be used to produce a tailored aluminum alloy product.
• FIG. 1 is a schematic, cross-sectional view of an additively manufactured product (100) having a generally homogenous microstructure.
• FIGS. 2a-2d are schematic, cross-sectional views of an additively manufactured product produced from a single metal powder and having a first region (200) of aluminum or an aluminum alloy and a second region (300) of an multiple metal phase, with FIGS. 2b-2d being deformed relative to the original additively manufactured product illustrated in FIG. 2a.
• FIGS. 3a-3f are schematic, cross-sectional views of additively manufactured products having a first region (400) and a second region (500) different than the first region, where the first region is produced via a first metal powder and the second region is produced via a second metal powder, different than the first metal powder.
• FIG. 4 is a flow chart illustrating some potential processing operations that may be completed relative to an additively manufactured aluminum alloy product. Although the dissolving (20), working (30), and precipitating (40) steps are illustrated as being in series, the steps may be completed in any applicable order.
• FIG. 5a is a schematic view of one embodiment of using electron beam additive manufacturing to produce an aluminum alloy body.
• FIG. 5b illustrates one embodiment of a wire useful with the electron beam embodiment of FIG. 5a, the wire having an outer tube portion and a volume of particles contained within the outer tube portion.
• the present disclosure relates to metal powders for use in additive manufacturing, and aluminum alloy products made from such metal powders via additive manufacturing.
• the composition(s) and/or physical properties of the metal powders may be tailored.
• additive manufacturing may be used to produce a tailored aluminum alloy product.
• the new aluminum alloy products are generally produced via a method that facilitates selective heating of powders to temperatures above the liquidus temperature of the particular aluminum alloy product to be formed, thereby forming a molten pool followed by rapid solidification of the molten pool.
